Automatic positioning and bag sucking device for large-diameter paper packaging bag

Abstract

This utility model provides an automatic positioning and suction bag device for large roll paper packaging bags, relating to the field of packaging bag suction technology. It includes a base plate, a support seat mounted on the top of the base plate, a lifting mechanism on the inner side of the support seat, a first mounting frame mounted above the support seat, a feeding chamber mounted above the first mounting frame, a pressure plate mounted on the inner side of the feeding chamber, and a discharging mechanism below the first suction cup and connecting frame. The device uses a suction bag assembly to replace traditional mechanical gripping. The first and second suction cups use negative pressure to suction the edge of the packaging bag opening, avoiding bag damage or detachment caused by improper gripping force, significantly reducing the packaging bag breakage rate.

Description

Technical Field

[0001] This utility model relates to the field of packaging bag suction technology, and in particular to an automatic positioning suction device for large roll paper packaging bags. Background Technology

[0002] In automated packaging production lines for large rolls of paper, such as commercial toilet paper and industrial toilet paper, the precise handling, positioning, and opening of packaging bags are the core links connecting "large roll paper conveying" and "finished product packaging," directly determining packaging efficiency and finished product quality.

[0003] Currently, the processing of large roll paper packaging bags in production lines largely relies on manual assistance or traditional mechanical clamping methods. Manual assistance requires operators to manually arrange the stacked packaging bags, align them with the conveyor path of the large roll paper, and open the bag openings. This not only results in low single-shift capacity but also easily leads to uneven bag openings and bag misalignment due to human error, which in turn causes subsequent sealing leaks and wrinkles in the finished product. Although traditional mechanical clamping devices can replace some manual operations, they have significant drawbacks—the clamping force is difficult to control precisely. Excessive force will damage paper or thin plastic packaging bags, while insufficient force will cause the packaging bags to fall off. Furthermore, the clamping mechanisms are mostly designed with fixed dimensions, requiring frequent disassembly and replacement of clamps when adapting to large roll paper packaging bags of different diameters and heights. This leads to long changeover times and severely disrupts production continuity. Therefore, this utility model proposes an automatic positioning and suction device for large roll paper packaging bags to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an automatic positioning and suction device for large-diameter paper packaging bags, which solves the problems in the prior art.

[0005] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: an automatic positioning suction bag device for large roll paper packaging bags, including a base plate, a support seat installed at the top of the base plate, a lifting mechanism provided on the inner side of the support seat, a first mounting frame installed above the support seat, a feeding chamber installed above the first mounting frame, a pressure plate installed on the inner side of the feeding chamber, a baffle plate installed at one end of the feeding chamber, a fixing frame installed at the rear end above the base plate, a first hydraulic cylinder installed on the inner side of the fixing frame, a first suction cup installed at one end of the first hydraulic cylinder, a connecting frame installed above the fixing frame, a second suction cup installed below the connecting frame, the first suction cup and the second suction cup being mutually compatible, a moving mechanism provided below the fixing frame, a second hydraulic cylinder installed at one end of the moving mechanism, a mounting plate installed at one end of the second hydraulic cylinder, a laser sensor installed at the middle position of one end of the mounting plate, third suction cups installed at the four corners of one end of the mounting plate, and a feeding mechanism provided below the first suction cup and the connecting frame.

[0006] A further improvement is that the moving mechanism includes an electromagnetic slide rail and an electromagnetic slider. The electromagnetic slide rail is installed at the bottom of the fixed frame, and an electromagnetic slider is installed below the outer side wall of the electromagnetic slide rail. The bottom end of the electromagnetic slider is connected to the top of the second hydraulic cylinder.

[0007] A further improvement is made in that: the lifting mechanism includes a cylinder, a guide sleeve, and a guide rod. The cylinder is installed at the bottom end of the support base, the guide sleeve is disposed through the corner of the support base, and a guide rod is disposed through the inside of the guide sleeve. The top end of the guide rod is connected to the bottom end of the first mounting frame.

[0008] A further improvement is that the feeding mechanism includes a second mounting frame, a feeding cavity, a guide rail, and a pushing assembly. The second mounting frame is mounted on the top of the base plate, the top of the second mounting frame is equipped with the feeding cavity, and one end of the feeding cavity is equipped with the guide rail.

[0009] A further improvement is that the pushing assembly includes an electric telescopic rod and a push plate, the electric telescopic rod is installed on the top of the base plate, and a push plate is installed at one end of the electric telescopic rod.

[0010] A further improvement is that two guide rails are provided at one end of the feeding cavity, and the guide rails are designed with one long and one short, and the inner side of the guide rails is provided with a groove.

[0011] The beneficial effects of this utility model are as follows: It replaces traditional mechanical clamping with a suction bag assembly. The first and second suction cups use negative pressure to adsorb the edge of the packaging bag opening, avoiding bag damage or detachment caused by improper clamping force, significantly reducing the packaging bag breakage rate. Simultaneously, the laser sensor and the second hydraulic cylinder work together to minimize bag removal position deviation, ensuring precise alignment between the bag opening and the large paper roll conveying path, greatly reducing bagging defects and subsequent sealing leaks. The feeding mechanism, utilizing the cooperation between the second mounting frame, feeding chamber, guide rail, electric telescopic rod, and push plate, can receive the large paper roll packaging bag after opening and bagging. The guide rail guides the packaging bag to slide smoothly into the feeding chamber, and the electric telescopic rod drives the push plate to automatically push the bag, avoiding low efficiency and product collisions caused by manual handling. This achieves continuous automation of the "bagging-feeding" process, reducing manual intervention, improving the overall efficiency of the large paper roll packaging production line, and ensuring the stability of finished product conveying.

Detailed Implementation

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes an automatic positioning and suction bag device for large-diameter paper packaging bags, including a base plate 1. A support seat 2 is installed at the top of the base plate 1. A lifting mechanism is provided on the inner side of the support seat 2. A first mounting frame 3 is installed above the support seat 2. A feeding chamber 4 is installed above the first mounting frame 3. A pressure plate 5 is installed on the inner side of the feeding chamber 4. A baffle plate 6 is installed at one end of the feeding chamber 4. A fixing frame 7 is installed at the rear end above the base plate 1. A first hydraulic cylinder 8 is installed on the inner side of the fixing frame 7. A first suction cup 9 is installed at one end of the first hydraulic cylinder 8. A connecting frame 10 is installed above the fixing frame 7. A second suction cup 11 is installed below the connecting frame 10. The first suction cup 9 and the second suction cup 11 are mutually compatible. A moving mechanism is provided below the fixing frame 7. A second hydraulic cylinder 14 is installed at one end of the moving mechanism. A mounting plate 15 is installed at one end of the second hydraulic cylinder 14. The middle of one end of the mounting plate 15... A laser sensor is installed at the location. Three suction cups 16 are installed at the four corners of one end of the mounting plate 15. A feeding mechanism is located below the first suction cup 9 and the connecting frame 10. In use, the packaging bag is placed inside the feeding chamber 4. The second hydraulic cylinder 14 is activated to move the third suction cup 16 forward. Simultaneously, the air pump is activated, and the third suction cup 16 sucks up the packaging bag. At this time, the electromagnetic slide rail 12 is activated to move the electromagnetic slider 13, thereby moving the sucked-up packaging bag to one end of the second suction cup 11. Then, the first hydraulic cylinder 8 is activated to move the first suction cup 9, which sucks up the packaging bag. Activating the first hydraulic cylinder 8 again moves the first suction cup 9, opening the packaging bag. At this time, a large roll of paper is fed into the packaging bag through an external feeding component for packaging. The laser sensor model can be TFmini-S. This laser sensor is connected to a microcontroller via wires, adapting to the real-time detection requirements of high-speed bag suction scenarios.

[0019] The moving mechanism includes an electromagnetic slide rail 12 and an electromagnetic slider 13. The electromagnetic slide rail 12 is installed at the bottom of the fixed frame 7. The electromagnetic slider 13 is installed on the lower side of the outer wall of the electromagnetic slide rail 12. The bottom end of the electromagnetic slider 13 is connected to the top of the second hydraulic cylinder 14. In use, the electromagnetic slide rail 12 is activated to drive the electromagnetic slider 13 to move, thereby driving the suction bag to move to one end of the second suction cup 11.

[0020] The lifting mechanism includes a cylinder 22, a guide sleeve 23, and a guide rod 24. The cylinder 22 is installed at the bottom of the support base 2. The guide sleeve 23 is inserted through the corner of the support base 2. The guide rod 24 is inserted through the inside of the guide sleeve 23. The top end of the guide rod 24 is connected to the bottom end of the first mounting frame 3. When the packaging bags are of different models and the height of the feeding chamber 4 needs to be adjusted, the cylinder 22 is activated. Under the guidance of the guide sleeve 23 and the guide rod 24, the first mounting frame 3 and the feeding chamber 4 are moved to adjust the feeding chamber 4 to an appropriate height, so that the device works better when in use.

[0021] The feeding mechanism includes a second mounting frame 17, a feeding chamber 18, a guide rail 19, and a pushing assembly. The second mounting frame 17 is mounted on the top of the base plate 1, and the feeding chamber 18 is mounted on the top of the second mounting frame 17. The guide rail 19 is mounted on one end of the feeding chamber 18. The pushing assembly includes an electric telescopic rod 20 and a push plate 21. The electric telescopic rod 20 is mounted on the top of the base plate 1, and the push plate 21 is mounted on one end of the electric telescopic rod 20. In use, the packaging bag slides down the guide rail 19 into the inside of the feeding chamber 18. At this time, the electric telescopic rod 20 is activated to drive the push plate 21 to move. The push plate 21 is used to push the large roll of paper for feeding, avoiding the low efficiency and finished product collision problems caused by manual handling. It realizes the continuous automation of "bag-feeding", reduces manual intervention, improves the overall efficiency of the large roll of paper packaging production line, and ensures the stability of finished product conveying.

[0022] Two guide rails 19 are provided at one end of the feeding cavity 18. The guide rails 19 are designed with one long and one short. The inner side of the guide rail 19 is provided with a groove. The design of the guide rail 19 can guide the packaging bag to slide smoothly into the feeding cavity 18 and guide the packaging bag.

[0023] Working principle: The operator first places the packaging bag inside the feeding chamber 4, then activates the second hydraulic cylinder 14 to move the third suction cup 16 forward. Simultaneously, the air pump is activated, using the third suction cup 16 to pick up the packaging bag. At this time, the electromagnetic slide rail 12 is activated, moving the electromagnetic slider 13, which in turn moves the picked-up packaging bag to one end of the second suction cup 11. Then, the first hydraulic cylinder 8 is activated, moving the first suction cup 9 to hold the packaging bag. Finally, the first hydraulic cylinder 8 is activated again, moving the first suction cup 9 to open the packaging bag. The large roll of paper is fed into the packaging bag through the external feeding components. Then, the first suction cup 9 and the second suction cup 11 release their grip on the packaging bag, and the packaging bag slides down the guide rail 19 into the unloading chamber 18. At this time, the electric telescopic rod 20 is activated to drive the push plate 21 to move. The push plate 21 is used to push the large roll of paper for unloading. When the packaging bags are of different models and the height of the loading chamber 4 needs to be adjusted, the cylinder 22 is activated. Under the guidance of the guide sleeve 23 and the guide rod 24, the first mounting frame 3 and the loading chamber 4 are moved to adjust the loading chamber 4 to an appropriate height.
